打破惯例！北斗系统新技术超过70%

打破惯例！北斗系统新技术超过70%1 2017年6月9日，参观者在第二十届中国北京国际科技产业博览会上参观展出的北斗卫星导航系统模型。 The State Council Information Office of China held a press conference on Monday on the completion and commissioning of the BeiDou Navigation Satellite System (BDS-3).

北斗三号工程卫星系统总师林宝军介绍说，卫星发射上天以后硬件没有办法更改了，要通过在轨赋能技术解决后面问题。

Lin Baojun, a chief designer of Beidou's third-generation satellite, said at a news conference on Monday in Beijing that once a satellite is launched, it is virtually impossible for its hardware to be modified, so designers and engineers need to optimize its operating system and inject new functions into the spacecraft on a regular basis.

就好像手机一样，手机可以通过软件升级来更新系统，我们可以下载一个新的APP，增加新的能力，我们这种能力在卫星上叫做“软件重构和在轨赋能”，当卫星有了这种能力之后，卫星在发射上天后就可以完成性能、能力的持续改进。

"This is like what we do with our mobile phones – we download a new app to give the phone more functions," said the designer from the Chinese Academy of Sciences' Innovation Academy for Microsatellites. "With this method, our satellites will be able to receive regular improvement in orbit."
